Long-term memory for Hermes, backed by HydraDB. Relevant context is recalled before each turn, and completed turns are saved in the background.
Good to know before installing
When selected as the memory provider, each turn's user message (as the recall query) and every completed user/assistant turn are sent over HTTPS to the HydraDB API (api.hydradb.com, or HYDRADB_BASE_URL) under HYDRADB_API_KEY.
From the plugin's catalog listing.
How to install
Install it. Hermes asks for any API keys it needs (this one needs HYDRADB_API_KEY, HYDRADB_DATABASE), then asks whether to turn it on.

Connect a Hermes agent through an existing Ando invitation and receive authorized messages.
Good to know before installing
Connects outbound to Ando (mcp.ando.so, api.ando.so, realtime.ando.so) with an agent API key stored at $HERMES_HOME/ando/connection.json (mode 600); Ando messages from the connecting member (or members the operator explicitly allowlists) start Hermes turns and the final reply, with any files it attaches, is posted back to Ando; message attachments are uploaded and downloaded through short-lived single-use links Ando issues (up to 20 MB each; received files are cached in the profile's Hermes cache); hermes ando connect edits gateway.platforms.ando in config.yaml.

Run Hermes on a Google Antigravity subscription through the official agy CLI, with agy as the model only: a generated custom agent removes agy's built-in tools, Hermes tools are exposed through an inventory-only MCP server with native function calling, and every tool call is handed back to Hermes. Fails closed on any non-Hermes tool step or silent agent fallback; pre-warms agy for fast tool loops.
Good to know before installing
Routes inference through Google's official agy CLI and counts against the Antigravity/Gemini subscription agy is signed in to; the plugin never reads, copies or links agy's credential files. agy runs in your real HOME with the gateway's environment; by default the plugin moves the agy conversation records created by its own idle pre-warmed processes under ~/.gemini/antigravity-cli/ to the trash (trash-put from PATH; ANTIGRAVITY_AGY_CLEANUP=off disables) and pre-warms up to 4 idle agy processes (~400 MB each).

Hosted memory for Hermes with a full history: see what your agent remembered, when it changed and why. Recalls relevant memories before each turn, adds bilinc_recall, bilinc_remember, bilinc_revise and bilinc_forget tools, and mirrors Hermes built-in memory writes. Maintained by ReARC Labs; free plan available.
Good to know before installing
Recall queries (the text of each message, when auto_recall is on), tool arguments, mirrored built-in memory writes, the Hermes session id and, only if memory.bilinc.capture_turns is turned on, each turn's user and assistant text are sent over HTTPS to bilinc.space under your BILINC_API_KEY; requests carry User-Agent bilinc-hermes/<version> and X-Bilinc-Client: hermes-plugin headers. Secret-looking strings are redacted before sending. Recall and writes run on background threads inside Hermes; no separate process, local database or telemetry.

Command Code CLI-key model provider with a live OAuth catalog property bridge, plan limits and failover classification.
Good to know before installing
Uses the CLI-internal api.commandcode.ai/alpha/generate endpoint and CLI client headers, sends the full conversation, tool schemas, cwd path and OS/Python version, and imports a static key from the read-only CLI credential file or a browser hand-off; no OAuth exchange takes place.

Ctx checkpoint
Community

Memory provider that archives the direct user/assistant transcript into a ctx knowledge store before every compaction, deterministically and with no LLM in the path, and hands the resulting block IDs to the compaction summary so the exact wording stays recoverable. Best-effort on any supported Hermes; with compression.checkpoint_required on Hermes 0.21.1+ it uses the fail-closed pre-compress checkpoint contract (#94639) and blocks compaction until the checkpoint is durable.
Good to know before installing
The turns about to be compacted (tool results and system prompts excluded, secrets redacted twice) are written through Hermes' MCP dispatch to the ctx server you configure in mcp_servers; the plugin holds no credentials, makes no other network calls and has no telemetry; it imports the core modules agent.redact, tools.registry and hermes_cli.config.

Answers an allowlisted direct message on your Meshtastic® radio.
Good to know before installing
Talks only to the MESHTASTIC_URL you set, over plain tcp, so channel keys and text travel unencrypted. An empty MESHTASTIC_ALLOWED_NODES answers nobody. A channel packet or a direct message without pkiEncrypted is never answered, because a channel key can forge a sender. Allowlisted nodes can prompt the agent, use tools until hermes tools turns them off, and approve one command at a time. An approval question is sent only when its line shows exactly the command /approve will run. A line that still goes out after that send was declined does not let /approve run it, and the next approval is declined once. Each direct message runs an agent turn on your model, and the agent cannot send on its own. No cron job comes with it; one the agent makes stays until hermes cron remove. Hermes main does not load this platform when plugins run in their own process. Node ids, sizes and times go to nodes.json in this profile's plugin-data and stay after uninstall. The message text is not stored. Not tried on a physical radio. Meshtastic® is a registered trademark of Meshtastic LLC. This site is not affiliated with or endorsed by the Meshtastic project.

Experimental model transport using the official Cursor Agent SDK. Requests go to Cursor through its official SDK. The plugin cannot enforce an included-only spending cap and never changes account spending settings. Instructions use a Cursor project rule, not a native system-role override. Permission and prompt-hierarchy equivalence remain unqualified. The plugin spawns Node and a local SDK agent, runs Git initialization in a plugin-owned workspace, and writes project rules, hooks, and SDK state under its own runtime directory. That state may contain private conversation data and currently remains on disk. Credentials come from Hermes's profile-scoped secret accessor. No credential store or vendor token file is read directly by plugin code. Text-only, buffered responses. The bundled model snapshot is not live entitlement discovery. Optional picker hooks require Hermes support. This plugin does not patch the desktop.
Good to know before installing
Spawns Node and a local Cursor Agent SDK worker per request (`npm ci` in the plugin dir installs Cursor's official native platform binaries from npm); sends the full conversation, system prompt and tool schemas to Cursor with your CURSOR_API_KEY; Cursor-native shell/file tools are denied by a fail-closed project hook and the run is cancelled if one fires, but that enforcement is not proven in every Cursor runtime; each request's workspace and conversation state stay under the plugin's runtime/ directory until you delete them.

Recall and save decisions, preferences and facts in your Kumiho Cloud workspace. Portable Agent Plugins v1 package with hosted OAuth MCP and six skills.
Good to know before installing
Connects to Kumiho's hosted MCP at https://mcp.kumiho.cloud/mcp (OAuth at control.kumiho.cloud, tokens held by Hermes); memory queries, including an automatic topic lookup near the start of relevant conversations, and approved captures are sent there; the server is marked `trust: untrusted`, so Hermes asks before every tool not annotated read-only. The optional backfill helper reads only files the user names and writes review packets to a new folder; Dream State can create a recurring Hermes cron task when asked (read-only by default). No local server, telemetry or background process.

Good to know before installing
Registers pre_gateway_dispatch (always returns None, so dispatch is never changed), pre_llm_call and gateway_platform_event hooks; keeps a bounded in-memory record of private-chat message ids, 60-character excerpts and reactions; writes nothing to disk, makes no network requests, starts no processes and reads no secrets.

Gives ChatGPT/Codex-subscription models the context window the backend actually accepts instead of the one its catalog advertises. Measured live on 2026-10-14: gpt-6.1-sol advertises 500K, caps at 872K and accepts 919,956 input tokens, while the -900k opt-in variant had silently stopped working because Hermes only raises a legacy 272K advertisement. The plugin reads the live catalog, writes one scoped model_overrides.<provider>.<model_id>.context_window entry per model (a documented step of context resolution, so no core patch), and ships a probe that bisects the API for the true ceiling because the refusal is a late SSE event, not an HTTP error. It also selects core's Codex-backed image provider so image_generate runs on the subscription with no OPENAI_API_KEY.
Good to know before installing
Uses the profile's Codex sign-in through Hermes's credentialed_provider_request (requires_auth: [openai-codex]); the plugin never reads auth.json and never holds a token, and network calls go only to chatgpt.com. Its only writes are scoped model_overrides entries and image_gen.provider (only when unset), through Hermes's atomic config writers; revert removes exactly what it wrote. No telemetry, no background processes, no shell commands, no self-updater. probe spends subscription quota (refused requests are free, accepted ones bill) and is never run automatically. Disclosure — uses the profile's Codex sign-in only through Hermes's credentialed_provider_request (requires_auth: openai-codex) and calls chatgpt.com only; its CLI and the model-callable codex_truly tool write scoped model_overrides context_window entries and image_gen.provider (only when unset) to config.yaml with no approval prompt, and `probe` sends large padding requests that spend subscription quota.

Self-hosted long-term memory on Qdrant: automatic per-turn prefetch and write-back, plus recall/remember/forget, guardrail rules and a knowledge graph; Hermes and any MCP-connected agent share one collection.
Self-hosted long-term memory on Qdrant: automatic per-turn prefetch and write-back, plus recall/remember/forget, guardrail rules and a knowledge graph; Hermes and any MCP-connected agent share one collection. Embeddings run fully local by default (sentence-transformers with Qwen/Qwen3-Embedding-0.6B, 1024d, about 1.2 GB from Hugging Face on first use; on Apple Silicon the model is pinned to the CPU, because PyTorch's MPS backend aborts the whole process under two overlapping encodes). A cloud embedder runs only when NEXUS_EMBEDDING_PROVIDER names it and its key is present, and a key that merely sits in the environment never selects one. Access levels fail closed: a memory, a protection rule or a graph label without a known level counts as the most restrictive. A local service on 127.0.0.1:9122 serves embeddings and the full MCP toolset; its /embed and /mcp routes demand a per-installation key (service_auth.key, mode 0600) and reject non-loopback Host/Origin, while the open /healthz answers liveness only. The plugin starts that service when Hermes cannot load the embedding stack, and it keeps running afterwards. Session-end fact extraction sends conversation text to the model endpoint from Hermes config.yaml, and the consolidation daemon to its configured model, which defaults to Hermes's own default model through local Ollama; reads ~/.hermes/.env and config.yaml; state and daily backups under ~/.nexus-memory; NEXUS_UPDATE_CHECK=1 opts into a GitHub release check.
Good to know before installing
When Hermes cannot load the embedding stack (and always on Apple Silicon unless NEXUS_EMBED_IN_HOST=1), the plugin starts `nexus-memory serve` on 127.0.0.1:9122 (embeddings, the full Nexus MCP toolset and a consolidation daemon that sends memory text to the Ollama endpoint at 127.0.0.1:11434 or NEXUS_OLLAMA_BASE under the model named by NEXUS_CONSOLIDATION_MODEL, nexus-memory.consolidation_model or Hermes's model.default, which can be an Ollama cloud model), and the service keeps running after Hermes exits; its /embed and MCP routes require a per-install key in ~/.nexus-memory/service_auth.key (0600) and a loopback Host/Origin; session-end fact extraction sends conversation text to the model endpoint in Hermes config.yaml, and the opt-in recall reranker (nexus-memory.rerank or NEXUS_RERANK=1) defaults to sending each query plus up to 20 memory snippets to that same endpoint using the provider API key it reads from config.yaml; reads ~/.hermes/.env and config.yaml; state and daily backups under ~/.nexus-memory; opt-in NEXUS_UPDATE_CHECK=1 adds a GitHub release check and an upgrade nudge to the system prompt.

Durable native memory for Hermes with LLM fact extraction. Conversations are distilled by the Hermes-configured LLM into searchable memories — facts, preferences and decisions with deduplication and importance — instead of storing turns verbatim, and are kept in Qdrant (embedded, self-hosted Server, or Qdrant Cloud) with configurable embeddings (default: local Ollama qwen3-embedding:4b at 2560 dimensions). The plugin registers a native MemoryProvider plus four scoped tools: qdrant_memory_search, qdrant_memory_add, qdrant_memory_update and qdrant_memory_delete. A SQLite WAL admission ledger makes every write idempotent and replayable across restarts with fail-closed recovery; scoped inventory, portable export and scope-aware deletion (list/export/delete-all with explicit single-agent vs all-agents semantics) ship in the same CLI, and `migrate mem0` imports existing Mem0 exports with resumable, verifiable runs.
Good to know before installing
Memory text is stored in the configured Qdrant store (embedded files under <HERMES_HOME>/qdrant-memory/qdrant by default, or the Server/Cloud URL you set), and memory text plus each turn's recall query are sent as plain text to the configured embedding endpoint (default local Ollama at http://127.0.0.1:11434; an OpenAI-compatible remote endpoint can be configured, and keyed endpoints must use HTTPS). Disclosure — after each primary-agent turn, at session end and before context compression, conversation text goes to the LLM configured in Hermes through the Hermes plugin LLM facade (a provider/model override needs the plugin's Hermes trust grant) to extract facts and to compare near-duplicate memories; that LLM may be a remote provider. Disclosure — the provider is selected with memory.provider: qdrant-memory; its settings live in <HERMES_HOME>/qdrant-memory.json (0600, secrets stripped on save). QDRANT_URL, QDRANT_API_KEY and EMBEDDING_API_KEY are read through the Hermes secret scope, but an api_key written by hand into qdrant-memory.json takes precedence, and `migrate mem0` reads the source Qdrant endpoint and any api_key from <HERMES_HOME>/mem0.json or --source-config.

CLIProxyAPI as native Hermes model providers: discovers each CPA provider group (Claude, Codex, xAI, Gemini, Kiro and others) and registers one profile per group on the wire its CPA executor accepts (Anthropic Messages, Responses or Chat Completions), with context windows and reasoning levels from CPA.
Good to know before installing
Sends model-list and inference requests, authenticated with the API key env var you name, to the CPA base_url you configure; with an optional management key it also makes bounded read-only GETs to CPA's management API; with an optional billing route it sends inference, and a model-list GET, to the gateway URL you configure, authenticated with the gateway key env var you name. Known limit: Hermes strips from agent subprocesses only the key env vars a registered provider declares, so the management key env var, and on a routed instance the CPA key env var, stay readable by agent shells.

Hwiki

Markdown wiki as Hermes long-term memory: plain files you and the agent edit together (Obsidian-compatible, git-versionable), local SQLite FTS5 search with optional qmd hybrid retrieval.
Markdown wiki as Hermes long-term memory: plain files you and the agent edit together (Obsidian-compatible, git-versionable), local SQLite FTS5 search with optional qmd hybrid retrieval. Inspired by the Karpathy LLM wiki.
Good to know before installing
Reads every Markdown file under the wiki folder you set (wiki_path, outside HERMES_HOME; untrusted_dirs, default raw/, excluded) and injects up to ~1,400 characters of matching excerpts into each turn; the agent appends dated notes only under <wiki>/<memory_dir> (default wiki/memory), and additions to Hermes's built-in memory are mirrored there by default (mirror_builtin_memory), so they land in a folder you may commit or sync; keeps an index at HERMES_HOME/hwiki-index.sqlite and config in HERMES_HOME/hwiki.json, and adds the wiki folder to hermes backup. Cron and subagent runs get read-only recall. No network with the default fts5 backend; the optional qmd backend runs the separately installed qmd CLI (npm @tobilu/qmd, Node ≥22), whose vector modes download local models (~0.3–1.6 GB).

OptChat-style endless memory for Hermes: an append-only verbatim log plus a binary summary tree, exposed as recall through the MemoryProvider ABC. Background compactor builds the tree with a cheap auxiliary model (call_llm task optchat_compact); prefetch returns a fixed-budget view of the whole history; optchat_zoom/optchat_date tools open any line down to the verbatim message.
Good to know before installing
Every turn's user messages, agent replies, tool calls and tool results (each result capped at 30,000 characters, after Hermes's secret redaction) are appended permanently to unencrypted owner-only files under $HERMES_HOME/optchat/, with no deletion or retention limit; a background compactor sends those messages and the surrounding summary view to your auxiliary model route (task optchat_compact) for summarization; each turn injects up to view_budget_chars (default 16,000) of that history into the model context.

Good to know before installing
Each user prompt (as a recall query), each user message and Hermes memory writes are sent to the agent-memory-es service at AMES_SERVICE_URL (default localhost:8123) with AMES_SERVICE_KEY; the model may store facts in shared team/common visibility tiers.

The Kimchi coding harness (kimchi.dev) as a Hermes model provider over ACP stdio — spawns kimchi --mode acp keeping the harness's permission prompts on (YOLO opt-in via KIMCHI_ACP_ARGS="--mode acp --yolo"), the harness owns its own auth, and completed tool calls surface as inline bullets in the reply.
Good to know before installing
Every turn spawns the local Kimchi CLI (`kimchi --mode acp`, overridable with KIMCHI_ACP_COMMAND / KIMCHI_ACP_ARGS) in Hermes's working directory and hands it the conversation. The harness calls kimchi.dev with its own stored login and runs its own shell, file and web tools. Its permission prompts stay on, and Hermes cancels them, so gated tools don't run, unless you opt in with KIMCHI_ACP_ARGS="--mode acp --yolo", which runs them with no approval prompt (not for shared gateway or cron use). To show setup status, it parses ~/.config/kimchi/config.json (or KIMCHI_CONFIG_PATH) only to check that a key is present; the key is never stored or sent by Hermes.

Local fact-store memory provider: SQLite with FTS5 keyword search (word forms in English, Russian, Spanish, French, Portuguese, Indonesian, German, Hindi, Arabic, Bengali, Italian, Turkish, Polish and Dutch; Russian and English words of the same root at a lower weight, from bundled DerivBase.Ru (Apache-2.0) and Open English Wordnet (CC BY 4.0) pairs; German compounds and German and Spanish irregular verb forms from bundled Wikidata Lexemes tables (CC0); Chinese, Japanese, Korean and Thai by character n-grams, Chinese also split into words with jieba's dictionary (MIT), Traditional and Simplified Chinese compared as one through a bundled OpenCC table (Apache-2.0), Japanese spelling variants through SudachiDict's (Apache-2.0); synonyms through keywords the agent gives when it stores a fact), trust scores, entities with aliases and HRR (holographic reduced representation) recall, with no API key, network or model calls unless an optional online feature is switched on: search by meaning (embeddings: on) or rescoring by a cross-encoder (rerank: on), both off by default.

Taken over from Nous Research's handoff copy (NousResearch/hermes-plugin-holographic) and maintained by itpartypattaya; since 0.1.1 it fixes probe/reason/related/contradict, non-atomic writes and the never-written retrieval_count, gates recall by relevance without repeats, flags duplicates and conflicts when a fact is added, and honours the provider contract (read-only subagent contexts, hermes_home, mirror metadata, backup_paths); since 0.8.0 it keeps the history of every fact (change / end / correct / revert, search and list as_of a date) and `forget` erases a fact with all its versions from the file; since 0.16.0 a name guessed from a fact's text must be shaped like one and stays provisional until a second fact or a person confirms it, and entities can be renamed or deleted (the facts stay). Since 0.18.0 an optional, experimental second stage reorders the recall candidates with a cross-encoder at a /v1/rerank endpoint that answers in Cohere's shape without a key, such as llama-server (rerank: on, off by default). It does not raise hits: on the maintainer's held-out set (126 questions) it cut non-target facts in the top fi

Memtomem
Community
Markdown-first long-term memory shared across your coding agents: a local memtomem MCP server plus six memory skills (index, recall, remember, search, setup, status).
Markdown-first long-term memory shared across your coding agents: a local memtomem MCP server plus six memory skills (index, recall, remember, search, setup, status). Notes live in ~/.memtomem and are searchable from Hermes, Claude Code, Codex CLI and Kimi Code. Runs at user scope.
Good to know before installing
The server is launched with `uvx --python 3.12` and downloaded from PyPI (memtomem[onnx]==0.6.9) on first start, with Python 3.12 if uv cannot find one; it runs as a stdio MCP server for the session and reads the directories you ask it to index. With a fresh BM25-only configuration nothing else leaves the machine; an existing memtomem configuration may enable Hugging Face model downloads, a remote embedding or LLM provider, Cohere reranking or search webhooks. At startup the server also reads the nearest .env found upward from its installed location inside uv's cache (normally ~/.env), setting variables not already present, outside Hermes's MCP environment filtering.

Dense semantic memory for Hermes, stored in a Qdrant collection you host. Each turn becomes one point — user and assistant text verbatim, no LLM summarization step — embedded on-device at 384 dimensions with fastembed (ONNX; the default install is 206 MB of runtime dependencies with no torch, versus ~1.2 GB when sentence-transformers was a hard dependency) and recalled by cosine search with an optional session_id payload filter, so a result quotes what was actually said. Registers 7 tools: qdrant_search, qdrant_upsert, qdrant_recall, qdrant_collect, qdrant_prepare, qdrant_forget (point-targeted deletion, dry-run by default, no delete-all), and md_search (local markdown knowledge index). An optional recall-indicator display, display.level (off | summary | verbose, default off), adds latency and collection to the chat indicator at summary and one numeric line per operation to the log at verbose — numbers and identifiers only, never recalled message text or search-result snippets (the md_search line also echoes the query you searched — your own input, not recalled content); it is separate from the older top-level progress knob (off | minimal | verbose), which gates status events. sentence-transformers is selectable on GPU hosts; both backends produce identical vectors for all-MiniLM-L6-v2, so switching backends needs no re-embedding. A circuit breaker (5 consecutive I/O failures, 120 s cooldown) degrades to no new memories instead of crashing, and is_available()/check_backend()/unavailable_reason() distinguish a misconfiguration from a dead server. Optional hybrid dense+sparse RRF search (default off): one config key enables dense+BM25 RRF fusion. A fresh collection declares the sparse vector at creation and an existing dense-only store gets it added in place (Qdrant >= 1.18) with one bundled backfill command; measured +0.024 recall@10 on the LongMemEval 1,000-example benchmark. INT8 quantization is not implemented. Local embedded Qdrant mode is not supported: the provider is REST-only and needs a reachable server.
Good to know before installing
All memory content (verbatim user and assistant turns) is stored in and read back from the Qdrant server at the configured url (default http://localhost:6333); QDRANT_API_KEY is only needed for Qdrant Cloud, is kept in .env and read through the Hermes secret scope, and is never written to config.yaml or qdrant.json. Disclosure — the only other outbound traffic is a one-time download of the embedding model weights (plus the 10 MB Qdrant/bm25 sparse model when hybrid is on) from huggingface.co (fastembed falls back to storage.googleapis.com/qdrant-fastembed if that fails); embedding runs on-device and no memory content goes to any other party. Disclosure — settings are stored in <HERMES_HOME>/qdrant.json (created 0600, no credentials) and last-operation status in <HERMES_HOME>/qdrant-status.json. Disclosure — md_search returns snippets of local markdown to the model from ~/.hermes/skills, the Obsidian vault at ~/Documents/hermes_default, ~/.hermes/hermes-agent/website and any path in the md_docs_roots key of qdrant.json; its index is built only when you run scripts/md_ingest.py and lives in <base Hermes home>/state/md-search/ (shared by all profiles).

Safe AI Labs as a Hermes model provider (`--provider safeailabs`, or Safe AI Labs in `hermes model`): an OpenAI-compatible API with one endpoint per region, the model list from its /v1/models and the context window of its fallback model declared.
Good to know before installing
Registers one model provider at import and nothing else (no tools, hooks, commands or threads); chat requests and the model list go to https://us.api.safeailabs.ai/v1 (or SAFE_AI_BASE_URL) through Hermes' own client with SAFE_AI_KEY, which Hermes reads; the plugin itself opens no connections, reads and writes no files and starts no processes.
From the plugin's catalog listing.
How to install
Install it. Hermes asks for any API keys it needs (this one needs SAFE_AI_KEY), then asks whether to turn it on.

Read-only Hermes Dashboard and Desktop plugin for inspecting built-in, holographic, Mem0, Honcho, Mnemosyne, Hindsight, and ByteRover memory.
Good to know before installing
Reads the active profile's memory files, provider configs and provider API keys (keys are never returned to the UI), and on user action sends search/recall/reflect queries with configured bank/peer/user IDs to the configured Mem0, Honcho and Hindsight endpoints (Hindsight Cloud default api.hindsight.vectorize.io) using those keys; ByteRover queries run the local `brv` CLI; for a local embedded Hindsight setup a contents read may start the `hindsight-embed` daemon; no memory is written.

LoreConvo memory provider: cross-surface persistent session memory with search, recall and structured memory items.
Good to know before installing
Stores end-of-session transcripts (truncated, including tool output) and Hermes memory writes in ~/.loreconvo/sessions.db, a store shared across all Hermes profiles and other LoreConvo clients, and injects context from those sessions into each turn; a Pro license enables a one-time Hugging Face embedding-model download; installs the loreconvo package (BUSL-1.1) with lancedb, fastembed and onnxruntime into the Hermes environment.
From the plugin's catalog listing.

Vornik Companion

Vornik as Hermes's hardened broker and long-term memory: Hermes holds no credentials; privileged work runs in operator-approved workflows on your own Vornik daemon.
Vornik as Hermes's hardened broker and long-term memory: Hermes holds no credentials; privileged work runs in operator-approved workflows on your own Vornik daemon.
Good to know before installing
Talks only to the self-hosted Vornik daemon at VORNIK_URL with VORNIK_BROKER_TOKEN (and VORNIK_MEMORY_TOKEN for memory); broker tools let the agent start operator-approved workflows on that daemon (writes are approved by a person in Vornik); when selected as memory provider it sends each turn's user query for recall, mirrors MEMORY.md and USER.md writes to the daemon, and asks the daemon to stop recalling (not delete) a mirrored entry that Hermes removes or replaces (/vornik-memory lists and /vornik-forget forgets what Vornik keeps); artifact tools expose only named outputs allowed by the approved workflow from completed runs and read bounded text or return short-lived binary download links from the daemon; task diagnosis tools (offered only when the daemon advertises companion-progress) return a broker task's execution events and closed error classes as the daemon serves them to a broker key; hermes vornik approvals on writes security.approval.transport (and vornik_companion.approval_namespace) to Hermes config, after which Hermes's own dangerous-command prompts (the redacted command text) are sent through the local vornikctl agent host-approval to the daemon and answered on the p

Windows desktop plugin that switches which Codex login and which Claude subscription account every local Hermes profile uses, with one idle-only, verified restart of the gateway (and, on Hermes before 0.22, of Hermes Desktop). Refuses while any profile is busy, restores the previous selection if a step fails, and writes a receipt that says whether the switch took effect.
Good to know before installing
Windows only. A switch rewrites, through Hermes's own commands, the Codex credential order in every profile's auth.json and the CLAUDE_SUBSCRIPTION_DIRECTSDK_CONFIG_DIR line in every profile's .env, so every profile that has the plugin enabled spends the same selected Codex login and the same Claude login (one Hermes-owned claude-auth folder; no token is copied between profiles). It reads Codex tokens from each profile's auth.json. On Hermes 0.22 and later it stops and restarts the gateway once Hermes's own idle proof and the gateway's drain report idle, and Hermes Desktop stays open and reconnects; on earlier Hermes it also reads the Desktop backends' dashboard session token from their process environment and closes and reopens Hermes Desktop (work started in the seconds after the idle check is cut off). It sends the target Codex token to OpenAI's usage endpoint and Claude login tokens to Anthropic's OAuth profile endpoint (also when the setup screen opens); if the target Claude login has expired it first runs the claude CLI once so the CLI renews its own token, which rotates that login's refresh token. No telemetry and no automatic account rotation.

Conxt governed memory provider — recall before each turn (personal, plus a team's approved memories), conversation capture in batches, and tools to search, remember, and propose team memories that a person approves in Conxt before anyone recalls them.
Good to know before installing
Each turn's message (first 500 characters) and the conversation's user and assistant messages are sent to the Conxt API at mcp.conxt.dev (or an https CONXT_BASE_URL you set) with your CONXT_API_KEY; tool results are not sent, but text the assistant repeats is. Every entry Hermes's built-in memory tool adds is also copied to your Conxt memory, and conxt_remember / conxt_propose send the memory text they are given. No telemetry, no shell commands, and nothing is written automatically from cron or subagent runs. Requires a Conxt plan that includes API keys.
